Gold Member Username: Thomas_gNM Post Number: 1352 Registered: Oct-05 | wat up i did wut u said and tried pvc port just to keep changing tha tuning to see what is best for my cvrz cuz itz easier than slot port changing and i think i finally found the magic numberz for my cvrz IMO. It gives loud low clean bass just as i like it so IMO i think itz da best SQL tuning mixture for cvrs. IMO Tha magic number for my cvrz is 32.75hz.  Thanx bro. |

Gold Member Username: Thomas_gNM Post Number: 1354 Registered: Oct-05 | I tried 32hz but IMO for my taste 32.75 is alot better. I have 4cuft enclosure tuned to 32.75 for both subs. So 2cuft for each. |

Silver Member Username: Talon_es93Post Number: 327 Registered: Mar-06 | would 32.75 only sound good with a reg. port or a slot one too? |

Silver Member Username: StnorrisEldridge, IA US Post Number: 523 Registered: Apr-06 | lol 32.75. seems like it wouldnt be much of a difference from 32. and how do u keep changing the tuning of your box like that. |

Gold Member Username: Thomas_gNM Post Number: 1357 Registered: Oct-05 | What i did was built another enclosure and got a HUGE piece of 4" pvc and then went to a calculator online and saw how long i had to cuz each piece for what ever tuning, so i cut em all at once then tried 1 at a time i did like 31hz-34hz and i liked it between 32.25hz-33hz but i think i liked 32.75 best so went with it, then i retuned my big enclosure with slot port for both cvrs to what i liked best and heard it a while ago and it soundz hella good. .D. i dont think it would matter which type to use but if u go wit pvc its easier, id recommend goin with 4" cuz of port noise i didnt have to sandpaper the ends and i didnt get no port noise, but like Rovin said the bigger tha diameter the longer it must be but for 31hz i only had to go like 12.5 inches long so it wasnt that bad. |

Gold Member Username: RovinTrinidad & T... Post Number: 8402 Registered: Jul-05 | GREAT - Happy 4 ya !!! glad that u got the result u wanted too - this is the exact reason y a installer friend of mine does majority of his ports with PVC cause with a picky customer or depending on the vehicle too when u do a permanent slot port box ur stuck with it . I'm surprised though that ur ear could find a difference with 3/4hz - u got the hearing of a cat/dog ! ...lol Here is another tip 4 ppl reading this & also want 2 try out what TJ did cut a hole in ur box about 1/8" wider than the pipe diameter u intend 2 use , cut a square piece of wood about 1" wider than ur pipe so if its 3" pipe then cut the square wood 5" x 5" & mark the middle & cut out the 3" hole & silicone the 3" pipe . So now this ^ comes like a port with a frame u can bolt on Now drill 4 holes 1/corner on this ^ & use T nuts/bolts & secure it onto ur box - so now u wont have 2 stick/unstick pipes onto ur box' surface , u can make a few of these of different lenghts/tuning & u just easily swap them out until u find a tuning u like ... |

Bronze Member Username: Crayola0Wisconsin Post Number: 47 Registered: Jun-06 | For a PVC port Does it matter how much of the tube is oustide of inside of the box if the length of the tube is what u want? If u put the tube all the way in will it work too? |
|
Gold Member Username: RovinTrinidad & T... Post Number: 8403 Registered: Jul-05 | what matters is the pipe INSIDE of the box - u do not want any pipe on the outside cause that will affect the tuning & way it sounds.... |

Bronze Member Username: Crayola0Wisconsin Post Number: 50 Registered: Jun-06 | are PVC ported boxes easier to make the slot port boxes? cause ive neva built a box and im gunna want a ported box. |
|
Bronze Member Username: Crayola0Wisconsin Post Number: 51 Registered: Jun-06 | And how do u attach the pvc pipe to the wood box? |
|
Gold Member Username: RovinTrinidad & T... Post Number: 8406 Registered: Jul-05 | advantages : its ALOT less work & uses far less space too its as simple as making a sealed box except u cut a hole 4 the pipe 2 fit in use this http://www.the12volt.com/caraudio/boxcalcs.asp |

Bronze Member Username: Crayola0Wisconsin Post Number: 53 Registered: Jun-06 | how would u use more than one port. how would u figure it out to make the frequency u want? Cause iv e seen some boxes with like 4 tubes. |

Gold Member Username: RovinTrinidad & T... Post Number: 8408 Registered: Jul-05 | other calculator which i have also used http://www.carstereo.com/help/Articles.cfm?id=31 extra pipe ports leads 2 alot more SPL & loss of some SQ in my experience ... this other site is 4 building slot ports http://www.subwoofertools.com/forum/ported-box.asp |
|
Bronze Member Username: Crayola0Wisconsin Post Number: 54 Registered: Jun-06 | But how would u figure it out? would u have to have shorter tubes? or what would i have to do? |

Silver Member Username: Talon_es93Post Number: 328 Registered: Mar-06 | whats better slot or round or does it matter? |

And u just need that perfect SQL mixture where u know it ur like wow. |
